Owners of these aircraft no longer need to install these specific ammeters to comply with Australian regulations.\n\n**Why this matters:**\nThis removes an outdated technical requirement that was unique to Australia and not based on manufacturer guidance. It reduces maintenance costs and regulatory burdens for operators of these older aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled","history":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled/history","analysis":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-31-32-electrical-power-indicators-modification-cancelled/documents"}}
